I was conducting a training for our local fire department yesterday evening, getting them up to speed on Rapid Shutdown. After the training, one of the fire fighters asked what they should do if they arrive at a home where a tree has fallen on a roof-mounted solar array. If the system has module level rapid shutdown, there shouldn't be any point in the array that exceeds the module Voc, and so it should be safe to cut the tree away. But what should I tell them to do if it is an older system without rapid shutdown? What would I instruct my crew to do if we were called to make it safe for the fire fighters? I have been thinking about that this morning and thought I would let the forum chew on it.
